Safety Information
Introduction
The Workshop Manual contains technical data, de-
scriptions, and repair instructions for the designated
Volvo Penta products or product versions. Make sure
that the correct workshop literature is used.
Read the following safety information and the
General Information and Repair Instructions in
the Workshop Manual carefully before starting
service work.
As a rule, all service work should be performed
on an idle engine. Some work, e.g. certain ad-
justments, require the engine to be running.
Approaching an engine that is running is a
safety risk. Remember that loose clothes or
long hair can fasten in rotating parts and cause
severe injury.
A careless movement or dropped tool while
working in the vicinity of an engine that is run-
ning, can in the worst case lead to injury. Ob-
serve caution on hot surfaces (exhaust pipe,
turbo, charge air pipe, starter element etc.) and
hot fluids in the lines and hoses of an engine
that is running, or has just been started. Refit
all guards dismantled during service work be-
fore starting the engine.
Make sure that the warning or information de-
cals on the product are always clearly visible.
Replace labels that have been damaged or
painted over.
Never start the engine unless the air filter is fit-
ted. The rotating compressor wheel in the turbo
can cause severe injury. Foreign objects in the
inlet pipe can also damage the machine.
Never use starter spray or the like. Explosion
risk in the inlet pipe. Risk of personal injury.
Avoid opening the coolant filler cap when the
engine is hot. Steam or hot coolant can spray
out, and built up pressure will be lost. Open the
filler cap slowly and release the overpressure
in the cooling system if the filler cap or cock
must be opened, or if a plug or coolant pipe
must be removed when the engine is hot.
Steam or hot coolant can flow out in an unpre-
dicted direction.
Hot oil can cause burn injuries. Avoid skin con-
tact with hot oil. Make sure that the oil system
is not pressurised before working on it. Never
start, or run the engine with the oil filler cap re-
moved in view of the risk of ejecting oil.
Important
The following special warning symbols are used in the
Workshop Manual and on the product.
WARNING! Warns of risk of bodily injury, seri-
ous damage to product or property, or that a se-
rious malfunction can occur if the instructions
are not followed.
IMPORTANT! Used to attract attention to things
that can cause damage or malfunction to prod-
uct or property.
NOTE! Used to attract attention to important informa-
tion, to simplify work procedures or handling.
The following list provides an overview of the risks
and cautionary procedures that should always be ob-
served.
Prevent the engine from being started by dis-
connecting the power with the main switch
(switches) and locking it (them) in disconnected
mode before the service work is begun. Attach
a warning sign in the cabin.

4
General Information
Stop the engine and close the bottom valve be-
fore working on the cooling system.
Only start the engine in a well-ventilated area.
Exhaust fumes and crankcase gases should be
led out of the engine compartment or workshop
when working in closed environments.
Always use protective glasses for work where
there is a risk of splintering, sparks, or splash-
ing of acid or other chemicals. The eyes are
extremely sensitive, and an injury can cause
blindness!
Avoid skin contact with oil! Prolonged or fre-
quent skin contact with oil can degrease the
skin, resulting in irritation, drying out, eczema,
and other skin complaints. Used oil is more dan-
gerous than new oil from the health care point of
view. Use protective gloves and avoid oil
drenched clothes and rags. Wash your hands
regularly, especially before meals. Use special
hand cream to counteract drying out, and to
simplify cleaning the skin.
The majority of chemicals intended for the
product (e.g. engine and timing gear oils, gly-
col, petrol and diesel oil) or chemicals for work-
shop use (e.g. degreasing agent, enamels and
solvents) are hazardous to health. Read the in-
struction on the pack carefully. Always follow
the given safety instructions (e.g. the use of
breathing protection, protective glasses, or
gloves, etc.) Make sure that other personnel
are not exposed to hazardous substances, e.g.
by inhaling the air. Make sure there is ade-
quate ventilation. Handle consumed and sur-
plus chemicals in the prescribed manner.
Observe extreme caution when tracing fuel
leaks in fuel systems and when testing fuel
nozzles. Wear protective glasses. The jet from
a fuel nozzle has a very high pressure and
penetrating force. The fuel can penetrate deep-
ly into bodily tissue and cause serious injury.
Risk of blood poisoning.
All fuels, in similarity with chemicals, are inflam-
mable. Make sure that naked flames, or
sparks, cannot lead to ignition. Petrol, certain
thinners, and hydrogen from batteries, are ex-
tremely inflammable and explosive when mixed
with air. Smoking is prohibited! Ventilate well
and take the necessary precautions before
conducting welding or grinding work in the im-
mediate vicinity. Always have a fire extinguish-
er handy in the workshop.
Make sure that rags drenched in oil and petrol,
including old fuel and lubricant filters, are
stored safety. Oil drenched rags can in certain
conditions self-ignite. Old fuel and oil filters are
environmentally hazardous waste, and together
with spent lubricant, contaminated fuel, paint
residue, solvent, degreasing agent and suds,
should be handed in to a waste handling unit
for destruction.
Batteries must never be exposed to naked
flames or electrical sparks. Never smoke in the
vicinity of batteries. Hydrogen develops when
batteries are charged, which in combination
with air forms an explosive gas. This gas is
highly inflammable and very explosive. One
spark from connecting the batteries incorrectly
is sufficient to cause the battery to explode and
cause injury. Do not touch the connection when
starting (risk of spark) and do not lean over the
batteries.
Never confuse the plus and minus terminals
when fitting the batteries. This can cause seri-
ous damage to the electrical equipment. Check
the wiring diagram.
Always use protective glasses when charging
and handling batteries. The battery electrolyte
contains strongly corrosive sulphuric acid. On
skin contact, wash with soap and plenty of wa-
ter. If battery acid gets into the eyes, rinse im-
mediately with water, and contact a doctor with-
out delay.
Stop the engine and switch off the power with
the main switch (switches) before working on
the electrical system.
Adjustment of the clutch should be conducted
when the engine is idle.

5
General Information
Use the lifting hooks mounted on the engine/
reverse gear when lifting the drive unit. Always
check that the lifting equipment is in good con-
dition and has the correct capacity for the lift
(weight of engine plus reverse gear and extra
equipment where appropriate).
For safe handling, and to avoid damaging the
components mounted on top of the engine, the
engine should always be lifted with a lifting bar
adjusted to the engine. All chains or wires
should run in parallel with each other and as
perpendicular to the top of the engine as possi-
ble.
Special lifting equipment may be required to
ensure the right balance and safe handling if
other equipment connected to the engine alters
its centre of gravity.
Never carry out work on an engine only sup-
ported by lifting equipment.
Never work alone when heavy components are
to be dismantled, even when safe lifting (e.g.
lockable block and tackle) equipment is used.
In most cases, two persons are required even
when lifting equipment is used: one to handle
the equipment and one to make sure that com-
ponents are not damaged. When working on-
board a boat always make sure in advance that
there is sufficient space to allow dismantling in
situ, without the risk of personal injury or dam-
age to materials.
WARNING! The components in the electrical
system and in the fuel system on Volvo Penta
products are designed and manufactured to
minimise the risks of explosion and fire. The
engine must not be run in environments sur-
rounded by explosive media.
When cleaning with high-pressure wash, ob-
serve the following: Never point the jet of water
at seals, rubber hoses, or electrical compo-
nents. Never use the high-pressure function
when washing the engine.
NOTE! Pressure pipes must not bent, turned,
or exposed to other strain. Replace damaged
pressure pipes.
Always use Volvo Penta recommended fuel.
See the instruction handbook. The use of inferi-
or quality fuel can damage the engine. The use
of inferior fuel in a diesel engine can cause the
control rod to jam and the engine to overspeed,
with the risk of personal injury or damage to the
machine. Inferior fuel can also lead to higher
maintenance costs.

General Information
About the Workshop Manual
This Workshop Manual contains technical information,
descriptions, and repair instructions for the standard
versions of the drive units 280, 280T, 280PT, 285,
285A, 290, 290A, 280-DP, 280-DP/PT, 290-DP,
290A-DP, SP-A, SP-A1, SP-A2, SP-C, DP-A, DP-A1,
DP-A2, DP-B, DP-B1, DP-C and DP-C1.
The Workshop Manual can show operations carried
out on any of the drives listed above. As a result the
illustrations and pictures in the manual that show cer-
tain parts on the drives, do not in some cases apply
to all the drives listed. However the repair and serv-
ice operations described are in all essential details
the same. Where they are not the same this is stated
in the manual and where the difference is considera-
ble the operations are described separately. The
Drive Designations and Series Number (PZ-No.) can
be found on the product plate. Please always include
both the drive designation and the PZ number in all
correspondence.
The Workshop Manual is primarily produced for
Volvo Penta service workshops and their qualified
personnel. It is therefore assumed that persons using
this manual have a basic knowledge of marine drive
systems, and can perform the relevant work of a
mechanical and electrical nature.
Volvo Penta continuously develops its products, and
therefore reserves the right to introduce modifica-
tions. All the information in this manual is based on
product data available prior to publication. Any
amendments or service methods of essential impor-
tance that have been introduced for the product after
this date are confirmed in the form of Service Bulle-
tins.
Spare parts
Spare parts for the electrical and fuel systems are
subject to different national safety requirements, e.g.
U.S. Coast Guard Safety Regulations. Volvo Penta
Genuine Spare Parts comply with these require-
ments. All types of damage resulting from the use of
non genuine Volvo Penta spare parts for the product
in question will not be regulated by the warranty
undertakings of Volvo Penta.

Repair Instructions
The work methods described in the Workshop Manual
are applicable for a workshop environment. The drive
has removed from the boat and is installed in an
overhaul fixture. Unless otherwise stated recondition-
ing work which can be carried out with the drive in
place follows the same working method.
The warning symbols used in the Workshop Manual
(see Safety Information for implication),
WARNING!
IMPORTANT!
NOTE! By no means cover everything since the
service work is conducted under a wide range of dif-
ferent conditions, and it is obviously impossible to
foresee everything. All that can be done is to point
out the risks that can occur from incorrect handling
when working in a well-equipped workshop with work
methods and tools approved by Volvo Penta.
Where Volvo Penta special tools can be used for
work procedures, these are described in the Work-
shop Manual. The object of special tools is to ensure
the safest and most rational work method possible. If
other tools or work methods are used than those rec-
ommended by Volvo Penta, then it is incumbent on
the person using them to ensure that there is no risk
of personal injury, damage, or malfunction.
In some cases, there are special directions and user
instructions for the tools and chemicals named in the
Workshop Manual. These directions should always
be followed even if there is no special mention of
them in the Workshop Manual.
Most risks can be prevented by means of taking ele-
mentary precautions and using common sense. A
clean workplace and a clean drive will eliminate
many risks of both personal injury and drive malfunc-
tion.
Above all when working with bearing unions and
sealing unions, it is extremely important to prevent
dirt or foreign objects from getting in, since this can
result in malfunction or reduce the life span of the re-
pair.
Our joint responsibility
Every engine consists of a large number of co-ordinat-
ed systems and components. The deviation of one
component from the technical specification can dra-
matically increase the impact on the environment from
what is otherwise a good engine. It is therefore ex-
tremely important to maintain the given tolerances, to
implement the correct adjustments where applicable,
and to use Volvo Penta Genuine Parts. The time
schedule in the engine’s maintenance schedule must
be followed.
Certain systems, e.g. components in the fuel system,
may require special competence and special testing
equipment. For environmental reasons certain com-
ponents are sealed at the factory and must not be
worked on by unauthorised persons.
Remember that most chemical products when incor-
rectly used can be damaging to the environment.
Volvo Penta recommends the used of biologically de-
composing degreasing agents for all cleaning of en-
gine components, unless otherwise stated in the
Workshop Manual. When working onboard boats
special care must be observed to prevent oils and
suds etc. unintentionally ending up the nature, e.g.
via the bilge water.
Tightening torques
Tightening torque for vital unions, which should be
tightened with a torque multiplier, are indicated in the
Workshop Manual, Technical data, Tightening tor-
ques and the manual’s work descriptions. All torque
readings are applicable for clean threads, screw
heads and mating surfaces. The torque readings re-
fer to lightly oiled or dry thread. If lubricants, locking
fluids or sealant are required for screw union, then
the type is indicated in the work description. For un-
ions where special torque denotations are not indi-
cated, the general tightening torque is applicable ac-
cording to the table below. The torque readings are
guide values, and unions do not need to be tightened
with a torque multiplier.

General Information
Safety instructions for
fluororubber
Fluororubber is a common material used in sealing
rings for shafts and O-rings.
Hydrofluoric acid is formed when fluororubber is
exposed to high temperatures (over 300°C/572°F),
and is strongly corrosive. Contact with the skin, eyes,
or respiratory passages, can lead to severe injury.
WARNING! Observe extreme caution when
working on engines that may have been ex-
posed to high temperatures, e.g. overheating
during seizing or fire. Seals must never be
burned off during dismantling, or burned up in
uncontrolled circumstances.
●●
●●
●Alwaysusechloroprenegloves(forhandling
chemicals) and protective glasses.
●●
●●
●Handle the removed seal in the same way a cor-
rosive acid. All residue, including ash, can be
strongly corrosive. Never use compressed air to
blow clean.
●●
●●
●Place the remains in a sealed plastic container
with warning label. Wash gloves under running
water before taking off.
The following seals are in all probability manufac-
tured of fluororubber.
Sealing rings for crankshaft, camshaft, and interme-
diate shafts.
O-rings, irrespective of position. O-rings for cylinder
lining seals are almost always made of fluororubber.
Note that seals that have not been exposed to
high temperatures can be handled normally.
Angular torque
For angular tightening the screw union is first tight-
ened with a given torque, after which tightening con-
tinues at a predetermined angle. Example: for 90°
angular torque the union is tightened an addition ¼
turn after the given tightening torque has been
achieved.
Lock nuts
Dismantled lock nuts should not be reused but re-
placed with new ones, since the locking properties
become inferior or non existent after multiple use.
For lock nuts with plastic inserts, e.g. Nylock®, the
tightening torque indicated in the table should be re-
duced if the Nylock®nut has the same nut height as
a standard solid metal hex nut. The tightening torque
is reduced by 25 % for screw sizes of 8 mm or more.
For Nylock®nuts with higher nut size, where the sol-
id metal thread is the same height as a standard hex
nut, the tightening torque as per the table is applica-
ble.
Strength classes
Screws and nuts are divided into different strength
classes. Their classification is indicated on the screw
head. A high number on the marking represents a
stronger material, e.g. a screw marked 10-9 is
stronger than a screw marked 8-8. It is therefore im-
portant when a screw union is dismantled to return
the screws to their original positions. See the spare
parts catalogue when replacing screws to ensure
that the correct version is used.

General Information
Sealant
A number of different types of sealant and locking flu-
ids are used on the engine. The sealant has different
properties for different union strengths, temperature
ranges, resistance to oil and chemicals, and for the
different materials and slot sizes in the engine.
It is therefore important to use the correct type of
sealant and locking fluid for those unions that require
them, in order to ensure satisfactory service work.
The Workshop Manual indicates in the relevant
chapters the compounds used when the drives were
manufactured.
The same compound, or a compound with equivalent
properties but of other manufacture, should be used
during the service work.
When using sealant and locking fluids it is important
that the surfaces are free from oil, grease, paint and
anti-rust agent, and that they are dry.
Always follow the manufacturer’s instructions con-
cerning application temperature and hardening times
etc. for the product.
Different basic types of sealant are used on the drive
and are characterised by:
RTV compound (Room Temperature Vulcanising).
Often used together with gaskets, e.g. sealing of
gasket joints or applied on gaskets. RTV compound
is clearly visible when the part has been dismantled,
and old RTV compound must be removed before the
union is sealed again.
The following RTV compounds are mentioned in the
Workshop Manual:
Volvo Penta part no. 1161099-5
(alternative Permatex®no. 3).
Old sealant is removed with denatured spirit.
Anaerobic compounds. These compounds harden
on the absence of air. The compound is used when
two solid parts, e.g. cast components, are fitted
together without a gasket. A common application is
also to secure and seal plugs, thread on studs, cocks,
and oil pressure sensors etc. Hardened anaerobic
compound is transparent and therefore the
compounds are dyed to make them visible. Hardened
anaerobic compounds are very resistant to solvents
and old compound cannot be removed. Before
refitting they are carefully degreased, after which new
sealant is applied.
The following anaerobic compounds are mentioned in
the Workshop Manual:
Volvo Penta part no. 1161053-2 (alternative Loctite®
243)
Volvo Penta part no.1161351-0 (alterantive Loctite®
603).
Polymeric compounds. The following polymeric
compounds are mentioned in the Workshop Manual:
Volvo Penta part no. 1141570-0, Sealant.

Corporation.
Loctite® is a registered trademark for Loctite Corporation.
